Izicelo kwiibhodi zeesekethe eziprintiweyo
Kwinkqubo yokwenziwa kweebhodi zeesekethe eziprintiweyo (emva koku zibizwa ngokuba yiPCB), iifiber ze-aramid zisetyenziselwa ukudibanisa izixhaso ze-chip lead ze-elektroniki ezixinana kakhulu.Olu hlobo lwenkxaso luneempawu eziqinileyo zokuqina, ngoko lunokuphepha amaphepha obhedu kunye ne-resin substrates emva kokufudumeza.iingxaki zokwahlukana.Kwishishini lombane, ukusetyenziswa kwezixhobo ze-aramid ukwenza iibhodi zePCB kunokunyusa amandla kunye nomgangatho weebhodi zesekethe.Olu hlobo lwebhodi yesekethe inobukhulu obuhle kunye ne-coefficient yokwandisa ye-3×10-6/℃.Ngenxa yesigxina se-dielectric ephantsi yebhodi yesiphaluka, ifanelekile ukuhanjiswa kwemigca ye-high-speed.
Xa kuthelekiswa nezixhobo zefiber zeglasi, ubunzima bale bhodi yesekethe buncitshiswe ngama-20%, ngaloo ndlela ukuqonda injongo yokuvelisa ubunzima bokukhanya kunye nenkqubo encinci yezixhobo zombane.Inkampani yaseJapan iphuhlise ibhodi yePCB enozinzo olungcono, ukuguquguquka okuphezulu, kunye nokuxhathisa ukufuma okunamandla.Kwinkqubo yokuvelisa,imicu ye-aramidzisetyenziswa kwi-meta-position, ekhawulezisa ukulungiswa kwezinto ezisekelwe kwi-epoxy-based resin.Xa kuthelekiswa nokusetyenziswa kwezinto ezichaseneyo, kulula ukusetyenzwa kwaye kunomsebenzi ongcono wokufunxa umswakama.IiPCB ezenziwe ngeentsinga ze-aramid zilula ngobunzima kwaye zinamandla ekusebenzeni, kwaye zinokusetyenziswa kwii-smartphones kunye neekhompyuter zethebhulethi.Ukongeza, iibhodi zeesekethe zangoku ezisekelwe kwifayibha ye-aramid ene-multi-layer structure inokupakisha i-electronics high-density, ezifanelekileyo ukuhanjiswa kweesekethe ezihamba ngokukhawuleza kwaye zisetyenziswe ngokubanzi kwishishini lomkhosi.
Usetyenziso kwi-Antenna Components
Ngenxa yokuba izinto ze-aramid zineempawu ezintle ze-dielectric, zisetyenziswe kwiindawo ze-radome, ezincinci kune-radome yeglasi yendabuko, enobungqongqo obuhle kunye nokuhanjiswa kwesignali ephezulu.Xa kuthelekiswa nesiqingatha sobude beradome, iradome ekwindawo ephakathi isebenzisa imathiriyeli yearamid ukwenzaincindi yobusiinterlayer.Izinto ezingundoqo zikhaphukhaphu ngobunzima kwaye ziphezulu ngamandla kunemathiriyeli engundoqo yeglasi.Ukungalungi ziindleko zokwenziwa kwemveliso.phezulu.Ngoko ke, inokusetyenziswa kuphela ekwenzeni amacandelo e-radome kwiindawo eziphakamileyo ezifana ne-shipboard radar kunye ne-airborne radar.Iinkampani zaseMelika kunye neJapan ngokudibeneyo ziphuhlise i-eriyali ye-radar parabolic, zisebenzisa izixhobo ze-para-aramid kwindawo ebonakalisa irada.
Ukususela uphando kwii-aramid fiberizixhobo ziqale kade kwilizwe lam, itekhnoloji iphuhliswe ngokukhawuleza.Isathelayithi ephuhlisiwe okwangoku i-APSTAR-2R isebenzisa i-honeycomb interlayer njengobuso obubonakalayo be-eriyali.Izikhumba zangaphakathi nangaphandle ze-antenna zisebenzisa izinto ze-para-aramid, kwaye i-interposition isebenzisa i-honeycomb aramid.Kwinkqubo yokuvelisa i-radome yenqwelomoya, i-para-aramid isetyenziselwa ukuthatha inzuzo yokusebenza kakuhle kwe-wave-transmitting yale nto kunye ne-coefficient ephantsi yokwandisa, ngoko ke ukuphindaphinda kwesibonisi sinokuhlangabezana neemfuno ezimbini zesakhiwo kunye nomsebenzi. .I-ESA iphuhlise i-sub-type enemibala emibini ene-diameter ye-1.1m.Isebenzisa isakhiwo se-meta-honeycomb kwisakhiwo sesandwich kwaye isebenzisa izinto ze-aramid njengesikhumba.Ukushisa kwe-epoxy resin kwesi sakhiwo kunokufikelela kuma-25°C kunye ne-dielectric constant yi-3.46.Ilahleko yelahleko yi-0.013, ilahleko yokubonakalisa ikhonkco yokuhanjiswa kolu hlobo lokubonisa kuphela i-0.3dB, kunye nokulahlekelwa kwesignali yokudlulisa ngu-0.5dB.
I-sub-type yemibala emibini ye-reflector esetyenziswe kwinkqubo ye-satellite e-Sweden inobubanzi be-1.42m, ilahleko yokuhanjiswa kwe-<0.25dB, kunye nokulahlekelwa kwe-reflection ye-<0.1dB.Iziko lelizwe lam lezoMbane liphuhlise iimveliso ezifanayo, ezinokwakheka kwesangweji ezifanayo njengee-eriyali zasemzini, kodwa zisebenzisa imathiriyeli ye-aramid kunye nemathiriyeli yeglasi yefiber composite njengezikhumba.Ukulahlekelwa kokubonakaliswa kwale antenna kwikhonkco lokuhambisa ngu <0.5dB, kwaye ukulahleka kokudluliselwa ngu <0.3 dB.
Usetyenziso kweminye imimandla
Ukongeza kwizicelo ezikule mimandla ingentla, iifiber ze-aramid zikwasetyenziswa ngokubanzi kumacandelo e-elektroniki anje ngeefilimu ezihlanganisiweyo, iintambo/iintonga ezikhuselayo, iziqhekezi zesekethe, kunye neziqhoboshi.Umzekelo: Kwintambo yothumelo eyi-500kV, sebenzisa intambo yokugquma eyenziwe ngesixhobo se-aramid endaweni yokugquma i-suspender njengesixhobo esithwala umthwalo, kwaye usebenzise intambo yokugquma ukudibanisa i-screw rod, enceda ukukhuthaza ukhuseleko olungaphezulu kwe-3. intonga ubukhulu becala yenziwe ngefayibha ye-aramid kunye ne-polyester ifayibha ephothiweyo, ibekwe kwivacuum, intywiliselwe kwi-epoxy resin imathiriyeli, kwaye imilo emva kokunyanga.Inokumelana ne-corrosion efanelekileyo ngexesha lokusetyenziswa, ubunzima obulula kunye namandla aphezulu, kwaye le nto iyasebenza kakuhle.Kumgca we-110kV, ukusebenza kokusetyenziswa kwe-insulating rods kuqhelekileyo, kwaye amandla ayo omatshini aphezulu ngexesha lokusetyenziswa, kwaye uneempawu ezintle zokumelana nokukhathala.Ekwenziweni koomatshini bombane, ukusetyenziswa kwezixhobo zefayibha ze-aramid kunokuphucula amandla ezinto kwaye kuthintele ukunxitywa okunzulu kumphezulu wokutshintshwa kokubumba.Inokutshintsha iintsinga zeglasi kwisixhobo sombane.Umxholo wefiber we-aramid fibers yi-5%, kwaye ubude bunokufikelela kwi-6.4mm.Amandla e-tensile yi-28.5MPa, ukuchasana kwe-arc yi-192s, kwaye amandla empembelelo yi-138.68J / m, ngoko ke ukuxhatshazwa kokugqoka kuphezulu.
Konke kwinto enye,izixhobo aramidzisetyenziswa ngokubanzi kwinkalo yokufakelwa kombane kunye ne-elektroniki, kodwa zikwajongene nobunzima.Ilizwe kufuneka liqhube iiprojekthi ezinjengeenguqu kunye nezixhobo zokuhambisa amandla ukukhuthaza ukukhuthazwa kunye nokusetyenziswa kolu hlobo lwezinto eziphathekayo kwi-insulation yombane, kwaye ngokuqhubekayo ukunciphisa izicelo zobugcisa kunye nemveliso yangaphandle.umsantsa phakathi.Ngelo xesha, izicelo eziphezulu eziphezulu kwiibhodi zeesekethe, i-radar kunye nezinye iindawo kufuneka zikhuthazwe ukuba zinike umdlalo opheleleyo kwiinzuzo zokusebenza kwezinto kunye nokukhuthaza uphuhliso olungcono lwelizwe lam lokufakelwa kombane kunye neendawo zombane.
